EL817 2-channel 5V 10A Relay Module - Deep Blue
Onboard EL817 photoelectric coupler a photoelectric isolating anti-interference ability strong. Onboard 5V 10A/250V AC 10A/30 V DC relays the relay long life can absorb 100000 times in a row. Module can be directly and MCU I/O link with the output signal indicator. Module has the diode current protection short response time
